Possible Causes

Broken bottom distributor, Cracked riser tube, Severely degraded resin, Incorrect gravel underbed

How to Fix / Troubleshooting

Safety: Shut off water and place the softener in BYPASS to prevent further resin migration.

  • Confirm resin in fixtures: Check faucet aerators and toilet tanks for small amber or tan beads, indicating resin loss.
  • Depressurize and open tank: Disconnect the control valve from the resin tank following US Water Systems instructions. Inspect the riser tube and bottom distributor for cracks or separation.
  • Replace damaged components: Install a new bottom distributor and riser tube if damaged. Remove and replace the resin bed if it is severely degraded or contaminated with debris.
  • Flush plumbing: After repairs, flush household plumbing by running multiple fixtures to clear remaining resin beads.
